|
||||||
|
**Project:** Tractatus Framework

||||||
|

|
||||||
|

|
||||||
|
|
||||||
|
## Overview
|
||||||
|
|
||||||
|
The Koha donation system uses the existing Stripe account from `passport-consolidated` to process donations in NZD (New Zealand Dollars). This document guides you through setting up the required Stripe products and webhooks.
|
||||||
|
|
||||||
|
**Account:** Same Stripe test account as passport-consolidated
|
||||||
|
**Currency:** NZD (New Zealand Dollars)
|
||||||
|
**Payment Types:** Recurring monthly subscriptions + one-time donations
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 1. Stripe Products to Create
|
||||||
|
|
||||||
|
### Product: "Tractatus Framework Support"
|
||||||
|
|
||||||
|
**Description:** "Support the development and maintenance of the Tractatus AI Safety Framework. Your donation helps fund hosting, development, research, and community building."
|
||||||
|
|
||||||
|
**Statement Descriptor:** "TRACTATUS FRAMEWORK"
|
||||||
|
**Category:** Charity/Non-profit
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 2. Price IDs to Create
|
||||||
|
|
||||||
|
### 2.1 Monthly Tier: $5 NZD/month
|
||||||
|
|
||||||
|
```
|
||||||
|
Product: Tractatus Framework Support
|
||||||
|
Price: $5.00 NZD
|
||||||
|
Billing: Recurring - Monthly
|
||||||
|
ID: price_<generated_by_stripe>
|
||||||
|
```
|
||||||
|
|
||||||
|
**After creation, copy the Price ID and update .env:**
|
||||||
|
```bash
|
||||||
|
STRIPE_KOHA_5_PRICE_ID=price_<your_actual_price_id>
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2.2 Monthly Tier: $15 NZD/month
|
||||||
|
|
||||||
|
```
|
||||||
|
Product: Tractatus Framework Support
|
||||||
|
Price: $15.00 NZD
|
||||||
|
Billing: Recurring - Monthly
|
||||||
|
ID: price_<generated_by_stripe>
|
||||||
|
```
|
||||||
|
|
||||||
|
**After creation, copy the Price ID and update .env:**
|
||||||
|
```bash
|
||||||
|
STRIPE_KOHA_15_PRICE_ID=price_<your_actual_price_id>
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2.3 Monthly Tier: $50 NZD/month
|
||||||
|
|
||||||
|
```
|
||||||
|
Product: Tractatus Framework Support
|
||||||
|
Price: $50.00 NZD
|
||||||
|
Billing: Recurring - Monthly
|
||||||
|
ID: price_<generated_by_stripe>
|
||||||
|
```
|
||||||
|
|
||||||
|
**After creation, copy the Price ID and update .env:**
|
||||||
|
```bash
|
||||||
|
STRIPE_KOHA_50_PRICE_ID=price_<your_actual_price_id>
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
### 2.4 One-Time Donation (Custom Amount)
|
||||||
|
|
||||||
|
**Note:** For one-time donations, we don't create a fixed price. Instead, the donation form sends a custom amount to Stripe Checkout. No Price ID needed for this - the code handles it dynamically.
|
||||||
|
|
||||||

|
||||||
|
|
||||||
|
## 3. Webhook Configuration
|
||||||
|
|
||||||
|
### Create Webhook Endpoint
|
||||||
|
|
||||||
|
**URL (Development):**
|
||||||
|
```
|
||||||
|
http://localhost:9000/api/koha/webhook
|
||||||
|
```
|
||||||
|
|
||||||
|
**URL (Production):**
|
||||||
|
```
|
||||||
|
https://agenticgovernance.digital/api/koha/webhook
|
||||||
|
```
|
||||||
|
|
||||||
|
### Events to Subscribe To
|
||||||
|
|
||||||
|
Select these events in Stripe Dashboard:
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
### After Creating Webhook
|
||||||
|
|
||||||
|
Copy the **Webhook Signing Secret** and update .env:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
STRIPE_KOHA_WEBHOOK_SECRET=whsec_<your_webhook_secret>
|
||||||

|
||||||
|
## 4. Testing Configuration
|
||||||
|
|
||||||
|
### Stripe Test Cards
|
||||||

|
||||||
|
|
||||||
|

|
||||||
|
| 4000 0000 0000 0341 | Attaching card fails |
|
||||||
|
|
||||||
|
**Expiry:** Any future date
|
||||||
|
**CVC:** Any 3 digits

|
||||||
|
|
||||||
|
## 7. Testing the Integration
|
||||||
|
|
||||||
|
### Test API Endpoint
|
||||||
|
|
||||||
|
```bash
|
||||||
|
curl -X POST http://localhost:9000/api/koha/checkout \
|
||||||
|
-H "Content-Type: application/json" \
|
||||||
|
-d '{
|
||||||
|
"amount": 1500,
|
||||||
|
"frequency": "monthly",
|
||||||
|
"tier": "15",
|
||||||
|
"donor": {
|
||||||
|
"name": "Test Donor",
|
||||||
|
"email": "test@example.com"
|
||||||
|
},
|
||||||
|
"public_acknowledgement": false
|
||||||
|
}'
|
||||||
|
```
|
||||||
|
|
||||||
|
**Expected Response:**
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"success": true,
|
||||||
|
"data": {
|
||||||
|
"sessionId": "cs_test_...",
|
||||||
|
"checkoutUrl": "https://checkout.stripe.com/c/pay/cs_test_...",
|
||||||
|
"frequency": "monthly",
|
||||||
|
"amount": 15
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Test Webhook Locally
|
||||||
|
|
||||||
|
Use Stripe CLI for local webhook testing:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# Install Stripe CLI
|
||||||
|
brew install stripe/stripe-cli/stripe
|
||||||
|
|
||||||
|
# Forward webhooks to local server
|
||||||
|
stripe listen --forward-to localhost:9000/api/koha/webhook
|
||||||
|
|
||||||
|
# Trigger test event
|
||||||
|
stripe trigger checkout.session.completed
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 8. Production Setup
|
||||||
|
|
||||||
|
### Before Going Live
|
||||||
|
|
||||||
|
1. **Switch to Live Mode** in Stripe Dashboard
|
||||||
|
2. **Create live webhook** endpoint:
|
||||||
|
- URL: `https://agenticgovernance.digital/api/koha/webhook`
|
||||||
|
- Same 8 events as development
|
||||||
|
3. **Obtain live API keys** (starts with `sk_live_` and `pk_live_`)
|
||||||
|
4. **Update production .env** with live keys
|
||||||
|
5. **Test with real card** (small amount)
|
||||||
|
6. **Verify webhook delivery** in Stripe Dashboard
|
||||||
|
|
||||||
|
### Production Environment Variables
|
||||||
|
|
||||||
|
```bash
|
||||||
|
NODE_ENV=production
|
||||||
|
STRIPE_SECRET_KEY=sk_live_...
|
||||||
|
STRIPE_PUBLISHABLE_KEY=pk_live_...
|
||||||
|
STRIPE_KOHA_WEBHOOK_SECRET=whsec_live_...
|
||||||
|
FRONTEND_URL=https://agenticgovernance.digital
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 9. Monitoring & Troubleshooting
|
||||||
|
|
||||||
|
### Check Webhook Deliveries
|
||||||
|
|
||||||
|
1. Stripe Dashboard → **Developers** → **Webhooks**
|
||||||
|
2. Click on your endpoint
|
||||||
|
3. View **Recent deliveries**
|
||||||
|
4. Check for failed deliveries (red icons)
|
||||||
|
|
||||||
|
### Common Issues
|
||||||
|
|
||||||
|
| Issue | Solution |
|
||||||
|
|-------|----------|
|
||||||
|
| Webhook signature verification fails | Ensure `STRIPE_KOHA_WEBHOOK_SECRET` matches Dashboard |
|
||||||
|
| Price ID not found | Verify Price IDs in `.env` match Stripe Dashboard |
|
||||||
|
| Redirects fail after payment | Check `FRONTEND_URL` is correct |
|
||||||
|
| Donations not recording | Check MongoDB connection and logs |
|
||||||
|
|
||||||
|
### Debug Logging
|
||||||
|
|
||||||
|
Enable detailed Stripe logs:
|
||||||
|
|
||||||
|
```bash
|
||||||
|
# In koha.service.js, logger.info statements will show:
|
||||||
|
[KOHA] Creating checkout session: monthly donation of NZD $15.00
|
||||||
|
[KOHA] Checkout session created: cs_test_...
|
||||||
|
[KOHA] Processing webhook event: checkout.session.completed
|
||||||
|
[KOHA] Donation recorded: NZD $15.00
|
||||||
|
```
|
||||||
|
|
||||||
|
---
|
||||||
|
|
||||||
|
## 10. Security Considerations
|
||||||
|
|
||||||
|
### Webhook Security
|
||||||
|
|
||||||
|
- ✅ Signature verification enabled (via `verifyWebhookSignature`)
|
||||||
|
- ✅ Raw body parsing for Stripe webhooks
|
||||||
|
- ✅ HTTPS required in production
|
||||||
|
- ✅ Rate limiting on API endpoints
|
||||||
|
|
||||||
|
### Data Privacy
|
||||||
|
|
||||||
|
- ✅ Donor emails stored securely (for receipts only)
|
||||||
|
- ✅ Anonymous donations by default
|
||||||
|
- ✅ Opt-in public acknowledgement
|
||||||
|
- ✅ No credit card data stored (handled by Stripe)
|
||||||
|
|
||||||
|
### PCI Compliance
|
||||||
|
|
||||||
|
- ✅ Using Stripe Checkout (PCI compliant)
|
||||||
|
- ✅ No card data touches our servers
|
||||||
|
- ✅ Stripe handles all payment processing
|
||||||
|
|
||||||
|

|
||||||
|
|
||||||
|
## 11. Next Steps
|
||||||
|
|
||||||
|
After completing this setup:
|
||||||
|
|
||||||
|
1. ✅ Test donation flow end-to-end
|
||||||
|
2. ✅ Create frontend donation form UI
|
||||||
|
3. ✅ Build transparency dashboard
|
||||||
|
4. ✅ Implement receipt email generation
|
||||||
|
5. ✅ Add donor acknowledgement system
|
||||||
|
6. ⏳ Deploy to production
